[sane-devel] Button Scan doesn't work for CS9000F

[Rolf Bensch]

Hi,

I found the problem by myself: The buffer in handle_interrupt() was too
small to handle the max. packet size of 64 bytes for the interrupt
endpoint of my CS9000F.

The button data also is different from the implementation. I'll commit
my changes in the next few days after some testing.

Cheers,
Rolf
